[PATCH v3 0/2] mm: batch mm counter updating in filemap_map_pages()

[Kefeng Wang <wangkefeng.wang@xxxxxxxxxx>]

Let's batch mm counter updating to accelerate filemap_map_pages(). 

v2:
- estimate folio type from caller and no need to return from
  set_pte_range()
- use unsigned long for rss

v3: 
- make is_cow to bool in patch1 and fix null folio in patch2
- retest, improvement same with v1

Kefeng Wang (2):
  mm: move mm counter updating out of set_pte_range()
  mm: filemap: batch mm counter updating in filemap_map_pages()
